Distillation column pressure variation can increase column capacity. Capacity gains can be achieved either from raising or lowering the pressure. Raising the pressure reduces gas density, thus allowing a greater vapor flow rate through the column, but it also reduces relative volatility, causing a higher reflux and reboil requirement for the same separation. Research and describe a scenario where applying a pressure variation to a distillation column might be preferable

I have certain operating conditions (pressure and temperature) given for a distillation column. Why are these conditions used? If there is a change in the operating conditions, is there an affect on the yield?

Prove that raising the pressure will increase melting point (Tm) of a metal. Use the Clausius-Clapeyron eqn., and remember that the enthalpy of a liquid is larger that the enthalpy of solid. Then consider the difference in molar volumes of the liquid and the solid

For the earth, a reasonable estimate of the variation of pressure with altitude can be made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. (a) Under these assumptions how does the pressure vary with altitude in terms of the altitude, y, molecular weight of the gas, M, gas temperature, T, and appropriate constants? (b) How does the number density...

a sieve plate column operating at atmospheric pressure is to produce nearly pure methanol from an aqueous feed containing 40 percent methanol. The distillate product rate is 5800 kg/h. 1. For a reflux ratio of 3.5 and a plate spacing of 18 in, calculate the allowable vapour velocity and the column diameter.

There are many avenues that companies can use to increase their capacity. Some are more permanent (hard ceiling capacity increases) some are more temporary (soft ceiling capacity increases). Suppose that you are running a company that produces a component for the automotive industry. Your current capacity is 5,000 units per week. You have calculated that you will need to increase your capacity to 7,500 units a week to meet your current demand. You are considering the following methods of increasing...

Keynes (1936) argued that, from a policy perspective, everything that can be achieved by a nominal wage cut can be more effectively achieved through an appropriate monetary policy. (a) Does this statement hold in the deficient-demand Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity? (b) Does this statement hold in the new Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity?
